Michael Dennis Mahoney

February 19, 1951 – June 20, 2025

Michael D. Mahoney [Age 74] passed peacefully at his home in Greenfield, New Hampshire on June 20, 2025 surrounded by his family and dear friends of many decades. A lifelong resident of the Granite State, Michael graduated from Milford High School in 1969 where he was a gifted athlete. He started college at the University of New Hampshire but his attendance was cut short by a life-threatening diagnosis of chronic kidney disease. His illness forced him to leave school and spend virtually all of his time struggling with his health. He eventually returned to college and graduated with distinction from Franklin Pierce College with a bachelor’s degree in finance.

Mike underwent an experimental kidney transplant with the organ donated by his mother, Cecile Mahoney Coy, in 1972. To aid with the cost of drugs and transportation, the people of Milford came together to support both Michael and another Milford boy, Tommy Byrd, undergoing the same ordeal. The generosity of the town through the Byrd/ Mahoney fund helped the Mahoney and Byrd families make it financially through this difficult time. As a result of Michael’s diligence, his dedication to diet, exercise, and a healthy lifestyle, his donated kidney continued working for over thirty-three years. In 2005 he received a second transplanted kidney from his sister, Micheleen G. Bagley, which prolonged his life for another twenty years.

Michael Mahoney was predeceased by his father, Stanley S. Mahoney, and is survived by his mother, Cecile Mahoney Coy, his elder sister, Micheleen G. Bagley and her husband Paul of Milford, NH, his younger sisters Sharon L. Galiatsatos and her husband Jerry of Silver Spring, Maryland, Marilyn M. McGuire and her husband Paul of New Boston, NH, Kyle J. Lyford and her husband Ernie of Gardner, Massachusetts, and numerous nieces and nephews.

Calling hours will be at Smith & Heald Funeral Home at 63 Elm Street, Milford, NH from 4:00 to 6:00 P.M. on Tuesday July 1, 2025. An interment will be held on Wednesday, July 2, 2025 at 11:00 AM, at the Greenvale Cemetery, Route 31 in Greenfield, NH.
